The complexity and amount of data rises. Modern graph databases are designed to handle the complexity but still not for the amount of data. When hitting a certain size of a graph many dedicated graph databases reach their limits in vertical or most common horizontal scalability. In this talk I´ll provide a brief overview about current approaches and their limits towards scalability. Dealing with complex data in a complex system doesn't make things easier... but more fun finding a solution. Join me on my journey to handle billions of edges in a graph database.

My slide deck from my SharePoint User Group Southampton presentation. This was an introductory overview to the CodePlex Project Community and a quick look at a few of the CodePlex Projects that I've recently reviewed.
SQLite is a widely popular database format that is used extensively pretty much everywhere. Both iOS and Android employ SQLite as a storage format of choice, with built-in and third-party applications relying on SQLite to keep their data. A wide range of desktop and mobile Web browsers (Chrome, Firefox) and instant messaging applications use SQLite, which includes newer versions of Skype (the older versions don’t work anyway without a forced upgrade), WhatsApp, iMessages, and many other messengers.
Forensic analysis of SQLite databases is often concluded by simply opening a database file in one or another database viewer. One common drawback of using a free or commercially available database viewer for examining SQLite databases is the inherent inability of such viewers to access and display recently deleted (erased) as well as recently added (but not yet committed) records. Here we examine the forensic implications of three features of the SQLite database engine: Free Lists, Write Ahead Log and Unallocated Space.

10 Things Learned Releasing Databricks Enterprise WideDatabricks
Implementing tools, let alone an entire Unified Data Platform, like Databricks, can be quite the undertaking. Implementing a tool which you have not yet learned all the ins and outs of can be even more frustrating. Have you ever wished that you could take some of that uncertainty away? Four years ago, Western Governors University (WGU) took on the task of rewriting all of our ETL pipelines in Scala/Python, as well as migrating our Enterprise Data Warehouse into Delta, all on the Databricks platform. Starting with 4 users and rapidly growing to over 120 users across 8 business units, our Databricks environment turned into an entire unified platform, being used by individuals of all skill levels, data requirements, and internal security requirements.
Through this process, our team has had the chance and opportunity to learn while making a lot of mistakes. Taking a look back at those mistakes, there are a lot of things we wish we had known before opening the platform to our enterprise.
We would like to share with you 10 things we wish we had known before WGU started operating in our Databricks environment. Covering topics surrounding user management from both an AWS and Databricks perspective, understanding and managing costs, creating custom pipelines for efficient code management, learning about new Apache Spark snippets that helped save us a fortune, and more. We would like to provide our recommendations on how one can overcome these pitfalls to help new, current and prospective users to make their environments easier, safer, and more reliable to work in.
UI Dev in Big data world using open sourceTech Triveni
He will be sharing his last 10 years of experience in UI Development for Big Data Analytics & ML world using available open-source plethora in the market. How 'UI dev' needs to target big data problems?
Key points to consider while choosing any open-source framework/library for the big data world.
Do you need to write a custom framework or use ready-made open source, when what to choose?
How dev can leverage open source frameworks like Angular, REACT to making big data apps faster?
How you can extend open-source BI tools like Kibana, superset graphana to make UI development tool?
How to show network big data using open source graph libraries?
How to deal with real-time data in Big data UI?
Why use & contribute to open source?
Design UI for future as in Big data world customer problems keep changing with time. Showcasing demo for our real customer's problems, how we achieved using these open source libraries.
As a Lead Developer I've been given a project to run from scratch. Zero lines of code in the repository, team and customer I haven't been working with before. In this speech I want to share a set of challenges team have faced. Present audience with a set of tools and practices proven to be helpful. Warn about wrong turns on the way to delivery to avoid
Lessons learned: Choosing your documentation systemPronovix
My team faced several questions a year ago when we started our brand new documentation portal. - Are we going to set up a platform based on an existing solution? - Are we going to create our own platform? - Are we going to use existing internal tools like Confluence?
To answer those questions we created our own process to guide our decision making: - First create a vision how your documentation should look like - Then test as many platforms as possible - Realize non are quite what you want - Realise you do not want to reinvent the wheel - Figure out how you can glue different solution together to get exactly what you want
We ended up with a mix of existing technologies like Doxygen and Sphinx, glued together with custom python scripts. This allowed us to rely on proven technology and still have the flexibility to tweak the result to our requirements, getting the best of both worlds. The biggest benefit of our solution is that it uses Unit tests to ensure that the documentation and the API stay in sync and developers are forced to update documentation when they change the API. This was one of the biggest benefits we gained from our new documentation system compared to the previously used.
In this talk I will go into detail how we created and implemented our process, how it worked out for us and why your team might want to follow a similar process.
At the end of the talk you will have a better understanding of - How to do research and compare documentation platforms - How to perform an informed decision for their documentation needs - How not quite reinvent the wheel and get what you want.
DevOps has been an emerging trend in the software development world for the past several years. While the term is relatively new, it is really a convergence of a number of practices that have been evolving for decades. Unfortunately, database development has been left out of much of this movement, but that's starting to change. As database professionals, we all need to understand what this important change is about, how we fit in, and how to best work database development practices into the established DevOps practices.
One of the cornerstones of the DevOps methodology is source control. When most people think of source control, they picture a tool - either a traditional, centralized system like TFS, or a newer, distributed system like Git. Source control is more than a tool, though; human processes and practices also play a critical role in an effective source control (and DevOps) implementation. In this session, we'll talk in depth about both types of source control systems and how you can effectively use source control for your databases.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
